| 摘 要： | 土壤盐渍化是困扰人类的五大土壤问题之一(王春裕等,1997).我国华北和滨海地区存在大量盐渍化土地,有些区域土壤含盐量达到1%以上(毛建华等,2005),严重影响着当地种植业生产的持续发展,也给园林绿化带来很大困难.

| Abstract: | The seed germination rate,germination index,germination value,vigor index,growth of radical and hypocotyls and activities of protective enzymes of Atriplex canescens were investigated under NaC1 and Na2CO3 stresses.The results showed that:1) While low NaC1 concentration(0.05 mol.L-1) promoted the germination rate,germination index and germination value of Atriplex canescens seeds,high NaCl,as well as Na2CO3,inhibited these parameters,and the inhibition was aggravated with the increasing salinity.Under Na2CO... |
